Allow me to waste your time.

Google upped its stalker factor this week by adding face recognition abilities to its image search. While currently unofficial and unannounced, users can now search for images that only contain faces by appending a query string onto the end of a search URL. For example, a general image search for “Ars Technica” produces a variety of image results, but when appending “&imgtype=face” to the end of the URL, all new results contain photos of people.
